WebAnother simple condition applies in the case where n is a power of two: (1) ... Since the discrete Fourier transform is a linear operator, it can be described by matrix multiplication. In matrix notation, the discrete Fourier transform is expressed as follows: ... Finite fields. If = () is a finite field, where ... WebA finite field K = 𝔽 q is a field with q = p n elements, where p is a prime number. For the case where n = 1, you can also use Numerical calculator. First give the number of elements: q = If q is not prime (i.e., n > 1), the elements of 𝔽 q must be described by a generator x whose minimal polynomial x over 𝔽 p is irreducible of ...
